VOX Threshold Control
This is a rotary knob that is used to select the VOX
threshold of the unit. See
below.
When rotated fully clockwise (cw), the threshold will be
at maximum and VOX ICS operation is disabled and ICS
PTT input is required for ICS operation.
When rotated fully counterclockwise (ccw), the threshold
will be at minimum (almost live).
To adjust the unit for
VOX
(Voice activated) use, the VOX control should be set fully ccw and then slowly rotated cw to
the point where no intercom audio can be heard. The VOX control should be adjusted for proper operation according
to the ambient noise.

This is a customizable deadfront annunciator activated
by an external switch.

applied to the CALL input from another user’s Audio
Controller - RX Mute - NVG or by a remote ‘call’ button
within the aircraft.
Note
: Check with your installing agency for confirmation of the operation of this annunciator. The legends
are interchangeable to allow customization.

ICS Volume Control
This is a rotary control used to adjust the volume of all
ICS audio to suit the ambient conditions. Rotating the
control completely cw gives rated level, and completely
ccw reduces the output to minimum level.
